C# 请参阅：C# 用 System.Xml 读 Freeplane.mm文件，生成测试用例.csv文件

Freeplane 是一款基于 Java 的开源软件，继承 Freemind 的思维导图工具软件，它扩展了知识管理功能，在 Freemind 上增加了一些额外的功能，比如数学公式、节点属性面板等。

打开 lazarus-IDE，创建 project: xml2csv , 编辑GUI界面，编写 unit1.pas  如下

unit Unit1;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, Forms, Controls, Graphics, Dialogs,
  StdCtrls, Crt; // ShellApi,

type

  { TForm1 }

  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Edit1: TEdit;
    Memo1: TMemo;
    OpenDialog1: TOpenDialog;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private

  public

  end;

var
  Form1: TForm1;
  fn1: String;
  fn2: String;

implementation

{$R *.lfm}

{ TForm1 }

procedure TForm1.Button1Click(Sender: TObject);
begin
  if OpenDialog1.Execute then
  begin
    fn1 := OpenDialog1.FileName;
    Edit1.Clear;
    Edit1.Text := fn1;
  end;
  if FileExists(fn1) then
  begin
    Memo1.Lines.LoadFromFile(fn1);
  end
  else
    ShowMessage(AnsiToUTF8(fn1+' 文件没找到'));

end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  fn1 := Edit1.Text;
  if FileExists(fn1) then
  begin
    // Simple one-liner (ignoring error returns) :
    //if ShellExecute(0,nil, PChar('mm_Xml_csv.exe'),PChar(fn1),nil,1) =0 then;
    SysUtils.ExecuteProcess('mm_Xml_csv.exe', Utf8ToAnsi(fn1), []);
    delay(100);
  end
  else
    ShowMessage(AnsiToUTF8(fn1+' 文件没找到'));

  fn2 := fn1 +'.csv';
  if FileExists(fn2) then
  begin
    Memo1.Lines.LoadFromFile(fn2);
  end;
end;
end.

copy mm_Xml_csv.exe to projects\xml2csv\  点击运行。

注意有中文文件名，需用 SysUtils.ExecuteProcess('mm_Xml_csv.exe', Utf8ToAnsi(fn1), []);
